PEG
The ULTRAPEG® product line is made up of ethylene oxide polymers. It is represented by the following general formula:
HO(CH2CH2O)nH
According to the degree of ethoxylation(n), products with different molecular weights andmelting points can be obtained, which allows the use of these products in various applications.
The ULTRAPEG® line is made up of:

The hydrophilicity of the polyoxyethylene chain from the ULTRAPEG® product line allows for the obtention of a hygroscopic polymer which is highly water soluble. By varying the molecular weight, liquid or solid products may be obtained, covering a wide range of viscosities and consistencies.
ULTRAPEG® 4000 F USP and ULTRAPEG® 300 F USP may be applied as supporting adjuvant for the dispersion of vitamins; as a binder and plasticizer for chewing gums and other food products produced in the form of tablets, as an auxiliary thickening agent and as a consistency agent in dietetic sweeteners and as a carrier in antioxidant blends. In these applications these products have a lubrificating, plasticizing, dispersant and solvent function.
